Abstract: In a multi-layer body with a carrier and at least one conduction layer first areas and second areas are galvanically isolated from each other by third areas. In the third area sections are omitted from conductor traces and replaced by replacement pieces. The multi-layer body thereby has an optically homogeneous effect (e.g. is uniformly transparent or uniformly reflective).

Abstract: The invention relates to a layered body, in particular one with two sheets of electric functional layers, as well as a use of this layered body for example in a touch screen with improved resolution. By changing the grid structure at the intersection areas a moiré effect can be avoided by superimposition of the patterns.

Abstract: The invention relates to a speed regulating device for a hydrostatic drive unit comprising a pump of variable feed volume and a motor in a hydraulic circuit, wherein the pump is driven by a drive motor of variable speed, and there is provided a regulating valve which controls the loading of a hydraulic adjustment device on the pump in dependence on the pressure differential in front of and behind an adjustable throttle arranged in the hydraulic circuit, in such a way that the feed volume is changed in inverse proportion to a speed change in the drive motor. It is the aim of the invention to produce a simple construction for the speed regulating device which can also be easily controlled in reverse operation and can be easily operated.
